Specification of Letters Patent.

Patented July 31, 1317.

Application'filedi'anuary 11, 1917. Serial No. 141,861.

To all whom it may concern Be it known that I, ALBERT N. SPANGELO, a subject of the King of England, residing at Thornhill, in the Province of Manitoba, in the Dominion of Canada, have invented certain new and useful Improvements in -Weed and Seed Destroyers; and I do declare the following to'be' a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use; the same.

My invention relates to a new machine for destroying weeds and seeds, andhas for one object the provision of a comparatively simple yet highly eflicient machine for turning under and burying noxious weeds and seeds at such a depth as to smother the same.

lVith this and other objectsin view, the invention resides in the novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being sup plemented by the accompanying drawings which constitute apart of this application and in which:

Figure l is a top'plan view of the improved machine;

Fig. 2 is a longitudinal sectionthereof' on the plane of the line 2 2 of Fig. 1-;

Figs. 3 and 4: are vertical transverse sections on the planes of the lines 33and H of Fig. '2; I

Fig. 5 is a perspective view of a fragment of the lever for adjusting one of the rock shafts" for raising and lowering the frame of the machine; and,

Fig. 6 is a similar view of thearched bar mounted rockably on said shaft for raising and lowering one of the plows.

In the drawings above briefly described, the numerals 1, 2'and 3designate threelongitudinally disposed draw bars, said bars and the connections therebetween constituting the main frame of the machine." The front end of bar 1 is directed laterally and secured to bar 2 while the front end of the latter is likewise bent laterally andsecured to the third draw bar 3. oblique brace 6 extends between the bars 1 and 2 and another between 2 and 3 to impart the necessary rigidity to the frame.

An ordinary turning plow 8 is carried by the rear end of the draw bar 3 and a furrow wheel 9 is disposed in rear of said plow, being carried by a vertical shaft 10 which is rockably mounted in a bearing carried by a V-shaped frame 11 suitably secured to the main frame of the machine. A crank arm 12 extends laterally from shaft 10 and by means of a link 13 is connected to one arm of a bell crank 14 fulcrumed on the front end of the frame. The bell crank l-it is connected with the tongue, 15 by means of a suitable link 16 ina' well known manner so that whensaid tongue is swung horizontally for turning the machine in either direction, the furrow wheel 9"will be turned to facilitate this operation.

A second plow 17 preferably in the form of a scoop is disposed in advance of and is offset laterally from the plow 8, the rear end of said scoop being pivoted at 18 to the downwardly turned rear ends of the draw bars '1 and 2 while the front end of said scoop is supported by a pair of depending links 19 which may be adjusted vertically by means yet to be described. A pair of bars 20 are pivoted at their front endsto the front end of scoop l7 and at their rear ends have slotted connections 21' with the rear extremities of the draw bars 1 and 2 so as to'limit the vertical adjustment of said scoop.

The scoop 17 delivers at its rear end into a trough 22 within which an endless belt conveyor 23 of any suitableconstruction is mounted, said conveyer being trained'around upper and lower rollers'24 as shown clearly in Fig. 2, said upper roller having a sprocket 25 driven from a sprocket chain 26 which is in turn driven by means to be hereinafter described.

A transverse horizontal rock shaft 27 is mounted at the front end of the frame and extendsabove the draw bars 1 and 2, said shaft having at one end a depending arm 28 upon which a groundwheel 29 ismounted, while a lever 30 is secured to the other end of shaft-27 for adjusting the same. A rack 31 and dog32 are provided for locking the'lever 80 in adjustedposit'ion and said lever carries a rack 33 cotiperating with a dog 3% for locking another lever'35 against movement. The lever 35 is either formed integrally with or otherwise joined to one arm of an archedbar 36 both of whose arms are provided at their ends with bearings 37 mounted rockably on the shaft 27, it being to the inner ends of said arms that the upper ends of the links 19 are pivoted.

By the construction just described, operation of lever 85 will raise and lower the plow with a ground wheel as.

or scoop 17 independently of the frame while rocking of shaft 2'? by means of lever 30 will cause the front end of said frame to rise or lower. 7

A second transverse shaft 38 extends between the draw bars 2 and 3 in at vance of shaft 27, said shaft having thereon a sprocket S9 for driving the chain 26 and a gear for rotating said sprocket. A pinion 41 meshes with gear i0 and is carried fixedly by the inner end of another transverse shaft %2 disposed below shaft 38 and equipped Shaft as is rotatably carried by a U-shaped frame at, the upper ends of the arms of this frame being rockably mounted on the shaft 38 so that forward and rearward swinging of said frame will cooperate with the mechanism at the other side of the machine to raise and lower the front end thereof. A lever a5 is secured to one arm of frame 44land is provided with a dog 46 cooperating with a fixed rack 47, said lever, dog and rack serving to adjust the frame at in the required manner and to lock it in the adjusted position.

In operation, the machine is drawn across the field upon which the weeds to be destroyed are growing, the plow 8 only being lowered on the first trip across or around the field. On the second tip, however, the plow or scoop 17 is lowered in addition to said plow 8, the latternow throwing the earth intothe furrow previously made and thus turning the weeds'and seeds under to the usual extent. This is not sufficient, however, to choke or smother the seeds but a layer of subsoil is deposited on the earth thrown upwardly from the furrow, by the endless belt conveyer 23, this. subsoil being taken by the plow or scoop 17 from the furrow previously formed. By thus covering the weeds and seeds, they will not sprout and will thus rot and fertilize the soil. To vary the depth at which the plow 8 operates, both levers 30 and will be adjusted to raise or lower the frame of the machine and when it is required to vary the depth of the furrow formed by the plow 17, independent adjustment of the latter may be made by operation of the lever 35.

Various changes may be made in the details of construction above described but regardless of these, the machine will be efficient and will fulfil a long felt agricultural need.

I claim 1. A weed and seed destroyer comprising a turning plow for forming a furrow to turn 7 the weeds and seeds under, a second plow in advance of and offset laterally from said turning plow to run in the furrow previously made by the latter, and a conveyer for carrying the subsoil rearwardly from said second plow and depositing it on the earth turned by said turning plow.

2. A, weed and seed destroyer comprising a frame, a turning plow carried by said frame to turn the weeds and seeds under, a second plow in advance of and offset laterally from said turning plow, a conveyer for carrying the subsoil rearwardly from said second plow and depositing it on the earth turned by said turning plow, a transverse rock shaft mounted on the front end of the frame and having a depending rigid arm on which a ground wheel is mounted, an arched bar having bearings at the outer ends of its arms mounted rockably on the aforesaid shaft, links depending from the inner ends of said arms of the arched bar and connected with the second plow, a lever secured to the rock shaft for adjusting the same, means for locking said lever in adjusted position, a second lever joined to the arched bar for adjusting the latter, a dog carried by said second lever, and a rack cooperating with said dog and carried by the first lever.

B. A weed and seed destroyer comprising a frame, a turning plow carried by said frame to turn the weeds and seeds under, a second plow in advance of and offset laterally from said turning plow, a conveyor for carrying the subsoil rearwardly from said second plow and depositing it on the earth turned by said turning plow, a transverse shaft at the front end of said frame, a U-shaped frame depending from said shaft, a second transverse shaft carried rotatably by said U-shaped frame below the other shaft, a ground wheel secured to said second shaft, driving connections between the two shafts, other driving connections between the upper shaft and the conveyor, and means for swinging the U-shaped frame forwardly to raise and lower the frame and for locking it in adjusted position.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
